Changes in MySQL Cluster NDB 6.1.11 (5.1.15-ndb-6.1.11) (2007-06-06)

MySQL Cluster NDB 6.1 no longer in development.
MySQL Cluster NDB 6.1 (formerly known as “MySQL Cluster
Carrier Grade Edition 6.1.x”) is no longer being
developed or maintained; if you are using a MySQL Cluster NDB
6.1 release, you should upgrade to the latest version of MySQL
Cluster, which is available from
http://dev.mysql.com/downloads/cluster/ .

This Beta release incorporates all bugfixes and changes made in
previous MySQL Cluster releases, as well as all bugfixes and
feature changes which were added in mainline MySQL 5.1 through
MySQL 5.1.15 (see Changes in MySQL 5.1.15 (2007-01-25)).

Note

Please refer to our bug database at
http://bugs.mysql.com/ for more details about
the individual bugs fixed in this version.

Functionality Added or Changed

Important Change:
The
TimeBetweenWatchdogCheckInitial
configuration parameter was added to enable setting of a
separate watchdog timeout for memory allocation during startup
of the data nodes.
(Bug #28899)

A new configuration parameter
ODirect causes
NDB to attempt using
O_DIRECT writes for LCP, backups, and redo
logs, often lowering CPU usage.

It is now possible to set the size of redo log files (fragment
log files) using the
FragmentLogFileSize
configuration parameter.

Bugs Fixed

Having large amounts of memory locked caused swapping to disk.
(Bug #28751)

LCP files were not removed following an initial system restart.
(Bug #28726)

Disk Data:
Repeated INSERT and
DELETE operations on a Disk Data
table having one or more large
VARCHAR columns could cause data
nodes to fail.
(Bug #20612)
